Pamnted June 22, 1920 the blending box 10, where it passes around aseries of bales l1 and thence over the apron or facing slip 12 on to thepaper base :formed on the wire apron, the distance between the outletsof t ie flow box 5 und the blendin r box 10, and the speed of movement othe wire apron 7 therebetween, being such that the paper base issuitably formed at the time 1t reaches the blending box for reception ofthe blending stock to produce the cloudy coating of desired appearanceand effect.

When the speed of travel of the wire apron is that commonly employed inthe manufacture of ordinary paper, the blending box l() is preferablylocated 20% to 25% of the distance between the slices 14, which levelthe paper base, and the couch roll 15 around which the Wire apronpasses, that distance, however, de )ending u )on the freeness of thestock. The mast rol f6, the table rolls 17 und the suction boxes 18, areprovided in accordance with well known practice in the art. After the)aper runs off the wire apron, it is dried, pressed and rolled likeother wall papers.

The paper stock is suitably colored as desired and is of about the sameconsistency ns that used in the manufacture of wall paper or otherpaper. The wood flour preferably consists of about 99 to 99-1f% ofwater, and the remaining part of wood fiber ground to roper fineness.The fiber is preferably ofppoplnr, although spruce, balm of gilead, basswood, white wood, pine, or almost any other kind of wood is suit ablefor the purpose. Regulation of the prolmrtion of paper stock und woodflour is made by men-ns of the valve 19.

The blending stock is generally white but may be of any suitable color.und preferably it has a thin consistency represented b about 99 partswater and 1 part wood fiber ground very fine. It is desirable that thestock be delivered uniformly and in regulated amounts on to the aperbase. For this urpose the blending ox is provided witl a number ofvalved inlets like 13 along the width of the wire aaron and the lastbaiie board 11 is prefer-n ily regulatable vertically to vary thethickness of the blending stock delivered to the facing strip 12, whichis preferably curved as shown to deliver the stock more uniformly sultof the udmixture, thereby rendering the cloud el'ect produced by theblending stock softer, more pleasing to the eye, and giving it a greaterdegree of, visionary depth.

It will be observed from Fig. 2 that the blending stock 20 is spreadlightly on a darker background of peper base 21 broken up or roughenedby a more or less regular occurrence of the wood flour particles 22, andforming thereby a cloud effect having visionary depth to a markeddegree. Furthcrmorc, the papel-is soft, impiessionistie and artistic,and is devoid of the harshness, sharp definition and glarecharacteristic of the so-cnlled marble papel' used for wrappin l1g. 3,illustrating the back surface of the paper, also serves to indicate howthe wood Hour particles 22 break up the reflecting surface so that theaddition of the blendin Stock to it produces the characteristic cloudeffect of visionary depth,

Havinfv thus described my invention, what I c aimis:

1. The method of making Wall paper with a cloud effect of visionarydepth, which consiste in forming a base of paperlstock combined withwood flour to break up the light reflecting surface of the pa er, andflowing n blending stock on the snr ace thereof.

2. A wall paper vhaving a base with alight reflecting surface broken upby woodilour, sind a blending stock forming a cloud effect thereon. y

3. A wall paper having a base of paper stock mixed with a materialbreakin up the light reflecting surface thereof, an also having ablending stock forming a cloud effect on the top surface of the base.

In testimony whereof I allix my signature.
